Kirstie Alley is busy sharing all her dirty little secrets. After she revealed she and Patrick Swayze were in love, Alley opened up about the feelings she developed for John Travolta after they first worked together in the '80s.

"Believe me, it took everything I had inside, outside, whatever, to not run off and marry John and be with John for the rest of my life," Alley tells Barbara Walters on "Good Morning America" in an interview that aired earlier today where she was promoting her book "The Art of Men."

So what stopped her? Well, Alley was married at the time to her second husband, Parker Stevenson -- the same man she emotionally cheated on with Swayze. She and Stevenson ended up divorcing in 1997, but considering all this news, it's a surprise they stayed together as long as they did.

Travolta and Alley worked together on the 1989 hit "Look Who's Talking," and Alley fell hard for her dreamy costar. Calling him "the greatest love of my life," Alley also denied rumors that he's gay.

"I know John. With all my heart and soul, he's not gay," she says. "I think it's some weird way, in Hollywood, if someone gets big enough and famous enough, and they're not out doing drugs and they're not womanizing, what do you say about them?"
